Medium Voltage Metering Units
SKIPPER is in field of manufacturing metering cubicles from 11KV to 33KV voltage ranges suitable for indoor / outdoor applications. The company has been a major supplier to various state electricity boards, utilities and industrial units requiring medium voltage connections. The units are compactly designed for indoor/ outdoor applications keeping in mind the space limitations. The metering cubicles are supplied with side entry or bottom entry for cables as required by the customer.
Mobile Capacitor Banks
SKIPPER executes World Bank Order for Nigerian Power System. Skipper Energy is supplying 33KV, 20MVAR, Mobile Capacitor Banks to the Power Holding Company of Nigeria (PHCN) for National Energy Development Project against Global World Bank tender.
These perfectly and innovative designed Capacitor Banks will improve Power Factor of PHCN Grid and will provide 20% to 30% saving in power by Reactive Power Compensation. The Power saved is power generated. These units can be shifted from one place to another as per the requirement with negligible dismantling, as the same have been designed to be mounted on trailers within a short time.
The compact substation incorporates our own make distribution transformer which is designed and made strictly as per iec60076 and is2026 specifications. The transformer compartment is fitted with removable bolted cover with louvers and sand traps. This design allows maximum ventilation and prevents ingress of sand or its accumulation in door cavities.

Main Distribution Board
Skipper mdbs are asta certified as per iec-60439-1 upto 2500a. The design is incorporated to cater all requirements / specifications of uae utility departments viz dewa, sewa, adwea, fewa etc. The skipper mdb construction of enclosures are form 2 type with ip 54 degree of protection.
the cubicle is suitable for both front and rear access. The galvanised sheets are subjected to chemical treatment before application of powder coating to ensure excellent corrosion resistance. The standard colour of the paint is ral 7032.
Expulsion Type Drop Out Fuses (Etdof-01)
Drop out fuses are used for fault protections in rural electrification, distribution system, industrial units having medium voltage connections both as primary and secondary back ups. The drop out fuse should operate before the connected equipment i.e transformer gets damaged. Generally D.O. Fuses are used as switching device along with protection and operated with the telescopic insulated rods from the ground level.
The operation of drop out fuse is extremely violent. Once the fuse blows off, the arc restrikes till it is quenched. Even few cycles are sufficient to damage the current carrying parts and the barrel.Skipper over a period of time has acquired expertise in the manufacturing of drop out fuses to withstand such short circuit currents.
Isolating Switches (Is-01)
Disconnecting switches are used for isolation of system under fault conditions or carrying out the maintenance work without disturbing the main supply network. The disconnecting switches are made as per relevant standards and the customers specifications. They are made with and without earth switches with mechanical / electrical interlocks, manually or motorized operated mechanism, having capacity to interrupt line charging currents. The current carrying parts are made of electrolytic grade copper. The contacts are designed to provide discharge free supply. The arcing horns ensure that main contacts remain safe during opening and closing operations thus giving a longer life to the switch. The metal parts are surface treated for protection against rust. The switches are tested from approved labs for high short circuit currents.
Isolating Switches (Is-02)
Down the years we have been working to better the switches in operation. Bearings and bushes were standardized to reduce the torque. Most of the manually operated switches can be operated with less than 30 kg operating weight.
we have also provided solid core insulator in most of the models to ensure operators safety in the event of main insulators leakage.
The unitized substation is a state-of-the-art-system which simplifies conventional substation design. M/s Skipper’s (ISO 9001 certified co.) fully engineered factory built design, is tailor made to customer needs. The company takes the total responsibility of engineering and building the complete USS, with fit and forgets technology. The Quality is guaranteed as all components of USS are subject to stringent internal quality checks. The housing is made from a composition of Aluzinc Sheet Steel having thickness of 2 mm,1.5 mm mild steel and 4mm structure member base frame and then powder coated.
Oil Filled Current Transformers
Oil filled current transformers in high voltage applications are still the preferred ones due to cost advantages and easy availability of the technology. They are available in live and dead tank versions depending on the customers requirements. In measuring and protection applications they can be manufactured in single or multi-core as well as multi-tap designs. Tap changing can also be on primary or secondary, however due to convenience of low current and low voltage, secondary tap changing is now a days the preferred trend.
L.V. Metering Panel
Ranging from 100A upto 800A, 415V, 50Hz, 3 PhasePowder coated sheet steel / GRP (Fire Proof) enclosure with canopy / rain shed.IP 54 degree of protection.Complete with Trivector meter (displaying upto 250 parameters), suitable Bus-Bars, class 0.5 CTs as per the ratio of the panel rating.Viewing window with toughened glass.Corrosion proof pad locking arrangements for utility departments to avoid tempering.
Load Centres / Distribution Board
Vacuum Circuit Breakers
The skipper make outdoor vacuum switchgear type pcvcb, is an outdoors, structure mounted, easy to install, vacuum switchgear for use in 12/36 kv system. It is a porcelain-clad construction similar to conventional outdoor high voltage switchgear and is a gang operated triple pole circuit breaker fitted with reliable and well-proven vacuum interrupters. Adequate phase clearances and height have been provided to meet standards and safety requirements. It is suitable for direct connection to overhead supply lines.
the type pcvcb design incorporates a minimum of moving parts and simplicity of assembly assuming a long mechanical and electrical life.
